James Pastoriza designed several
circuits at Philbrick. After leaving Philbrick in the early sixties,
he founded Pastoriza Electronics, which specialized in
Analog-to-Digital converters. One famous converter from his product
line was the ADC-12U, which converted 12bits from an Analog input
voltage to an output digital code in 10us.

In 1969, Analog Devices bought
out Pastoriza Electronics and started it's march to dominate the ADC industry.

Greetings:

James (Pasty) Pastoriza, formerly with Philbrick, was a very
good friend and fraternity brother of mine at MIT in the 1940s.
Here he is in a group photo of the Iota Mu chapter of the Phi
Gamma Delta fraternity at MIT. Jim is #4. His son now resides
in the San Francisco area.

Those missing are myself and several others enrolled in the Navy
V-12 at MIT.

Gosh, I never would have recognized him [Pastoriza]. During the time
I knew him (ca 1960 onward) he seemed much older, perhaps
because he had lost all his hair.

But then I probably wouldn't have recognized myself in a class (WPI
'48) photo if I had not met myself until 1960.

Sorry--I left out an important detail: The perhaps gifted company
(we'll call it Electronic Prototypes) had a room that was George
Philbrick's hideaway lab. Jim Pastoriza had worked for the Air Force
Cambridge Research Lab. and was a customer of Electronic Prototypes.
That's probably how he and George Phibrick met, and became good
friends. Hence the "drinking buddy" comment.

The last time I saw Pasty was on a business trip to Boston in the
1960s. We took a long walk around the Fenway andhad a great
conversation. He was a brilliant guy, kept close to himself, and
could be somewhat abrupt on occasion. I don't know how he died, but
it was much too soon. Some years ago, I tracked his son to San
Francisco. I believe he is now in ethesda.

How and where and for how long did you know him?

Hi George:

I knew him peripherally as a drinking buddy of George Philbrick
during the '60s. The rumor was that George actually gave him the
company that became Pastoriza Electronics. George got to own that
company because he had to bail out the owner so many times from debt
(they did really good work, building a lot of the Philbrick products,
so he needed to protect the property and employees), that the IOUs
amounted to ownership. But he gave it to Jim because he didn't want
to own another company! I wonder if it's true.

In January, 1969, I joined Analog Devices, and fortuitously they were
acquiring Pastoriza Electronics at about the same time (PE was one of
just a couple of modular converter manufacturers; it was the very
beginning of he low-cost modular converter era, and Pastoriza was our
key to entry. So for the next year or two I got to know Jim, and he
was just about as you described him. When he heard that my wife
played the piano, he became interested in possibly playing
violin-and-piano duets (he played the violin in a chamber group), and
actually lent her some music to look atbut nothing ever came of
it. He invented a seminal monolithic quad switch that gave us an
immediate technological advantage. After that, he "retired"
(with the proceeds from selling his company), and I saw no more of
him. A few years later I was saddened to hear that he had died of
cancertoo young! He was about my age, but I've somehow survived
to my 80s.

Best wishes,

Dan

Dear Dan:

Thank you very much for the historical sketch of Jim Pastoriza's role
in post WWII electronics. As I recall, I was rather surprised that he
had retired so soon after his creation of Pastoriza Electronics. Your
explanation of his owning the assets of Philbrick and those of PE,
and then selling them so that he could retire makes perfect sense. I
had been unaware of the possibility that "Philbrick gave him the
company", though I would not been too surprised if he did,
knowing the kind of guys they were and the spirit of the times.

I knew that Jim was brilliant, but I did not know that his talents
extended to music and the violin! Have you heard him play?

Jim had a particularly good friend outside our fraternity at MIT:
Kemon Taschiaglou. One would always see them palling around at house
parties. Kemon went to Lincoln Labs and lived/lives in Lincoln, MA. I
have little doubt that the two of them exchanged all sorts of ideas
in electronics. Kemon is of Turkish descent and was a very upbeat and
most likable guy. I recently ran across a photo of his wife at their
Boston wedding in 1960:

In the summer of 1958, I took my then recently widowed mother to the
beach north of Santa Monica, CA. There was a large Gazebo-like beach
bar where we relaxed and had some Tom Collinses and watched the surf
and the surfers. It was a perfect sunny day. Suddenly, I caught the
form of a familiar figure, some 75 yards away, doing some wild body
surfing. It could be none other than Kemon! I yelled at him and he
came over and joined us. Small World. I think he was here on a
business trip.
